that ODASD(SCI) conducted with the DOD Components in 2010-2011) 

4. BACKGROUND: 

 a. DOD 4140.1-R (reference 3a) established policy for DOD Unique Item Tracking (UIT). A FLIS 

UITDC provided a standard means to systematically identify that an item is subject to a UIT program. 

b. ADC 172 (reference 3b) established UITDC value ‘UID’ for use with National Stock Numbers 

(NSNs) which fell under Item Unique Identification (IUID) policy criteria (i.e. they require IUID marking), 

but which were not part of established DOD unique item tracking (UIT) programs. By definition all assets 

tracked in DOD UIT programs by serial number, are subject to IUID, however, all items subject to IUID are 

not part of DOD UIT programs. UITDC ‘UID’ was a “place holder” value as ADC 172 noted that business 

rules for system/functional use of UITDC ‘UID’ had not been identified. ADC 172 further noted that as 

UID logistics policy requirements evolved, the concept for the UITDC ‘UID’ may shift. The concept has 

shifted as noted in paragraph c below, rendering a requirement for UITDC value ‘UID’ obsolete. 

c. ODASD(SCI) has convened a series of workshops (reference 3c) to address integrated 

requirements for IUID in logistics business processes under Serialized Item Management (SIM). As part 

of the SIM process, a requirement for a new FLIS code for IUID to identify levels of management 

intensity was agreed upon, rather than focus on specific programs as UIT did. 

(1) The concept of levels of management intensity was created to distinguish each IUID item 

by the degree of lifecycle traceability required on that item across the DOD supply chain. 

(2) Based on the nature of the item, the level of visibility and accountability will vary. There 

are two levels of intensity: standard and high. Accountable records are managed by unique 

item identifier (UII) for both levels of intensity, but owner records are also managed by UII 

for high intensity items. 
d. On March 29, 2011, the DOD MILSTRAP Administrator/SPRC Co-Chair confirmed with DLA 

Logistics Information Service (formerly Defense Logistics Information Service (DLIS)) that no NSNs 

have been assigned FLIS UITDC ‘UID’. 

5. CHANGE:

 a. Change in detail: Remove code value ‘UID’ and associated guidance from the UITDC, 

as shown below: 

FLIS CODE NAME: UIT Designator 

FORMAT: 3 position alphanumeric code 

PURPOSE: Used to indicate that an item requires DoD level unique item tracking (UIT) and to 

identify a DoD UIT program associated with the UIT requirement. Also used to identify items 

which fall under the DoD Unique Identification (UID) criteria but which are not subject to 

a DoD UIT program. All UID items subject to a DoD UIT program will be identified by a 

UITDC other than ‘UID’.

b. Alternatives: None. 

6. REASON FOR CHANGE: To eliminate UITDC value ‘UID’ in light of evolving policy 

and change of direction for FLIS coding for IUID. 

7. ADVANTAGES AND DISADVANTAGES:

 a. Advantages: Eliminates a code established as a placeholder that will not be used in 

light of evolving IUID logistics policy. Eliminates confusion that could arise from a FLIS 

UITDC value of ‘UID’, when logistics policy direction has shifted to development of a separate 

and distinct FLIS code for IUID focused on levels of intensity. 
 b. Disadvantages: None. 

8. NOTE ANY REGULATIONS OR GUIDANCE: (IF APPLICABLE): Evolving 

logistics policy for IUID to be published in DOD Manual (DODM) 4140.1 Draft DODM 4140.1 

is in OSD pre-coordination prior to being released for formal review by the DOD Components.. 

9. ESTIMATED TIME LINE/IMPLEMENTATION TARGET: Effective immediately. 

10. IMPACT: 

 a. FLIS UITDC. Revise the UITDC list to eliminate code value ‘UID’.

 b. DLMS Data Elements: No impact to DLMS Data Elements 

c. Publication: Revise DOD 4000.25-M, DLMS, Volume 2, Chapter 19, to remove all 

mention of UITDC value “UID’ as follows (changes are identified by bold italic strike-through): 

 (1) Section C19.7.3. 

 a) Combine paragraph C19.7.3.1. with C19.7.3. and delete paragraph number 

C19.7.3.1. and the header “UITDCs other than code ‘UID’ as follows: 

C19.7.3. Apply UITDC to National Item Identification Numbers (NIINs). (See section C19.27 for 

assigned UITDCs.) C19.7.3.1. UITDCs other than code ‘UID’. Ensure the integrated materiel 

manager (IMM) applies the UITDC to every NIIN comprising the DoD-level program, for which a 

UITDC isn’t already assigned. The IMM assigns UITDCs to an NIIN based on direction by the 

DoD Component UIT central control point. UITDC provides the DoD Components a systematic 

means to identify that a NIIN is subject to UIT and subject to these procedures. 

 b) Delete paragraph C19.7.3.2: 

C19.7.3.2. UITDC ‘UID’. UITDC ‘UID’ was approved for use to identify items which fall under 

OSD Item Unique Identification (IUID) policy criteria, but which are not part of a DoD UIT 

program. Assets which have UITDC ‘UID’ are not required to be tracked in accordance with 

UIT procedures/requirements. Components must establish the necessary interface between 

acquisition and supply to ensure that the IMM assigns UITDC ‘UID’ to NIINs which fall under 

IUID policy/criteria, but which are not part of a UIT program, and are therefore not subject to 

these procedures.

 (2) Section C19.27 and Table C19.T2, revise as follows: 

C19.27. UNIQUE ITEM TRACKING DESIGNATOR CODES (UITDC). The Federal 

Logistics Information System is the authoritative source for the UITDC. UITDC indicates that 

an item requires DoD level UIT and identifies a DoD UIT program associated with the UIT 

requirement. UITDC can also identify items which fall under the DoD IUID criteria but 

which are not subject to a DoD UIT program. All IUID items subject to a DoD UIT 

program will be identified by a UITDC other than ‘UID’. See section C19.7.3 for application 

of UITDC. UITDC are as follows:
